Perencanaan Dan Fabrikasi Sistem Propulsi Mini Sumber Penggerak Baterai (ACCU) Sebagai Alat Bantu Renang Atau Snorekeling

Abstract

The electric propulsion system in this system is a useful system to facilitate movement in
water. Using an electric motor as a driving source supplied by a battery (ACCU). Which is packaged
using a watertight box to protect the motor and drive source from water. The components used in this
propulsionelectric system use watertight components, so that they can function optimally when used
for snorekeling. Using 4 inch PVC pipe. Effective electrical power using a 12 VDC 6 Ampere Hours
(AH) accu voltage source with 72 watts of power. The electric motor as a driving device uses a
12Volt DC motor with a maximum power of 400 Watts. The propeller shaft uses PA material with a
diameter of 10 mm and is lightweight and does not rust when used. For the propeller using stainless
alluminum material with a plate 2 mm thickness 3 leaves with a diameter of 5 inches. The basic
working principle of this tool is to convert electrical energy from the battery into rotational energy in
the motor, then the motor rotation is coupled with the propeller shaft used to rotate the propeller,
which will ultimately produce thrust to the user.
